微粒子复合体是一种极具潜力的功能材料,研究它与电磁波的相互作用,有着重要的理论和实际意义.从材料的构成看,微粒子复合体属于异质性材料.因此,一般采用有效媒质法研究它的物理参量.为此,我们利用平均场理论,建立微粒子复合体介电特性的有效媒质理论模型,并利用这一模型结合具体的复合体系统讨论微粒形状和表面异质层等因素对渗流转变的影响. Microparticle complex is a kind of potential functional material, and its interaction with electromagnetic waves has important theoretical and practical significance.From the composition of the material, the particulate composite belongs to the heterogeneous material.Therefore, the commonly used effective media Law to study its physical parameters.To this end, we use the average field theory to establish an effective medium theory model of the dielectric properties of the composite particles and the use of this model combined with the specific complex system to discuss the particle shape and surface heterogeneous layer and other factors Impact on the change of seepage.
